-rorAL-Annrne WEIGHING-SCALE.

To all whom it may concern Be it known that 1, WILLIAM B. Moon, a citizen of the United States, and a resident of the city of Sandusky, in the county of Erie. and State of Ohio, have invented certain new and useful Improvements in Total- Adding Weighing-Scales, of which the following is a full, clear, and exact description,

reference being had to the accompanying drawings, forming a part of this specification.

My invention relates to attachments for v'weighing scales, whereby various loads weighed on the scales may be registered on the counting wheels and the totals of the amounts weighed added up, and the especial rear elevation of the same. Fig. 3 is a side 1 elevation with the casing removed. Fig. 4

is a vertical section, taken on the lines 4, 4,

is a similar section, looking toward the right. Fig. 6 is a plan view of the bracket and rock shaft for unlocking the adding mechanism. Fig. 7 is a plan View of the push rod and pin for releasing the crank. Fig. 8 is a vertical section of the dash-pot for steadying the -movement of the dial pointer. Fig. 9 is a parts are inclosed is indicated by 1, and

Application filed May 18, 1911. Serial No. 628,000.

ing indicated by the movement of the pointer over a graduated dial, indicated at 7 8 is a rod connecting the indicating mechanism with the platform scales,.not shown, and the upper end of this rod is coupled with a frame 13 to which is attached a heavy coiled spring 9, under the extension of which the various weights are indicated. The up- ;per end of this coiled spring is connected with. a cross bar 10., suitably guided in the frame, and the tension of the spring is regulated by the rod 11 connected therewith, upon the outer end of which is mounted the thumb nut 12.

The sliding frame 13, suitably guided and supported in the framework, carries the rack 14, which engages a pinion 15 on the shaft 5, so that-the loads on the platform actuate the rack and pinion to move the pointer over The nut 12 is employed to balance the scale in the usual way. The

adjustment of the nut .12 raises or.lowersthe-rod 11 and through it the frame 13 and rack '14, and thus the pointer is adjusted to the zero position;

In order to steady the movement of the pointer, I provide a dash-pot 16, consisting of the usual closed cylinder 17, supported by standards 18, while in the cylinder is mounted the piston 19 with piston rod 20 connected with the projecting plate 21 on the rack frame 14. The plunger piston is made in two parts, with slots 22 registering with each other for'the passage of the retarding medium in the cylinder, and one of the parts is mounted on a. solid rod which is located inside the hollow rod of the other part, so that one portion of the piston can be rotated and the other held in any desired position by the set screw 23 to regulate the extent of the slotted opening in the piston, and thus to regulate the action of the dash The shaft 5 on its inner end carries the large gear wheel "24 secured thereon, which gear rotates with the pointer 4, andwhen the weighing scales are used without reference to the adding devices, this gear rotates without function.

The parts above'described form an ordinary weighing seales construction; and as described, the scales can be used in the ordinary way.

Mounted in line with the shaft 5 is a second shaft 25. This shaft is supported in suitable bearings in the "framework end to.

rise on its inner end, keyed thereto, 'en-- larged driving gear 26 the some size end number of teeth as tbe'gear 2 The shaft on its outer end carries the'cronk 2?, w its handle 28, by means of which the scat 25ond gear 26 may be rotated. Suitably pivoted in the lower portion of the freme is a rock shaft 29, upon which are secured side arms 30, 31, extending horizontally and parallel to each other, and in the outer end of these arms is mounted the shaft upon which are secured a pair of similar pinions 33, 34:, which pinions ere arranged to err gage respectively the gears 24 and 26. Se-

. cured also on the shaft 29 and extending in the opposite direction is an arm 35, which is connected at 38 by connecting bar 36 with the outer end of a casing 37, which is in turn pivotally mounted at 39 in the framework of the machine. This casing 37 carrice the counting wheels 41 of. a total adding mechanism, which is actuated by a pinion 40, mounted in the casing. This pinion is arranged to engage the large gear 24 mounted on the shaft 5. The pinions 33, 34, and the pinion 40 of the registering mechanism are normally separate itrom and out of engagement w-ith'their respective gears 24- and 26. lt will be evident, however, that by rocking the shaft 29 the pinions 33 and 3 on the shaft 32 and the pinion 40 on the register casing will each be thrown into mesh with their respective gears, so that the rotation of the gear 26 by the crank handle 28 will, through the intermesliing pinions 33 and 34-, rotate the gear 2%, which rotation will in turn register its movement on the counting wheels. In order to effect this movement, an arm d2 is rigidly fixed to the arm 31 ot' the pinion frame, w ich arm projects upwardly into the pathway of s horizontsl pin d3 on the push rod 44 which is mounted in the frame to slide inwardly, and is held in position on the frame by the plate 45 secured over the horizontal slot in the framework in which the rod slides. As the arm 42 is fixed to the arm 31, this inner movement of the push rod rocks the pinion carrying frame and rock shaft 29 to throw the piuions 33, 34, into mesh. with their re spcctivc gears. At the some time the rock ing of the shaft 29 through the arm 35 and connecting bar 36 draws ClOV/ll the register casing and brings the pinion 40 into mesh with the gear 24.

The crunlc lumdlo 28 is normally prevented from being rotated by the pin 46, against which the lower end of the crank abuts at 47. This pin slidcs loosely in an opening through the framework 3, and on its inner end curries on upwurdly projecting pin 48 which engages in a diagonal slot 19 in a lateral plate 50, which is secured to the-side ct lillo push l )(l 44-, so that us the push rod is actuated the pin l6 will be withdrawn from the pathway cf the crank handle.

I in order to loci: the pinion frame and pinions 33 34 in their engaging p0 sitinn'with their respective gears, the outer end of the pinion frame is provided with a pin '51 proyecting upwardly with the shaft 32 at the end opposite the arm 42, which oin projects into the pathway of a pawl 55 fixed on rock shaft 56, ournaled at the bottom of the Irame. This pawl is provided with a notch 57 to engage the pin 51 and hold the pinions in mesh when a weight has been placed on the scales. Before the scales are actuated, however, this pawl is prevented from engaging the pin 51. Secured on the end of the pawl, preferably by screws 58, is

a dog 59 which projects upwardly to engage a horizontal arm 60, which 13 secured to u short shaft $1, mounted in a bracket 62 se-' cured to the framework (see Fig. 6). This shaft 61 also carries a shorter-m 63, projecting in the opposite direction and directly underneath it downwardly cxtendingbsr (3%, which is secured adj'ustably by pin and. slot connection 65 to the sliding rack bar 14.

pawl 55, which is spring-pressed inwardly by the coiled spring (30 lroin engaging the pin 51. The moment any loud placed on the scales and the sliding frame 13 with its down ".irdly extending bar 64- is actuated, the shaft (Sl will be rocked, raising the arm 60 and releasing the dog and pawl. When a weight, therefore, has been placed on the scales and the push rod 44 is actuated to rock the pinion frame, the pin .31 will be raised and the pawl will engage the pin and hold the pinions in mesh. in the event that the push rod 44 is not actuated, however, to raise the frame, the use of the scales to weigh articles, the wcigl'its of which are not to be registered, the pawl 55 does not operate when released by reason or" the projection 67 engaging the pin 51.

In order to hold the push rod 44 in its inner position, I provide :1 latch 68 which is pivoted to the frame 3 above lllC push rod, and the cud (39 of this latch 68 engages in the recessed block 70 sooured on the iuncr end of the push rod 44. This engagement of the latch 68 with the push rod, llUWQVOl, is not permitted until a weight is pldccmoullio scales and the pawl 53:) allowed lo cugngc the pinion frame to hold lhc pinimls in mesh. The movcmrnt in ense is provided with a cam slot 72, which is engaged by a pin 78 on the inner end of the latch 68. The lower surface of the cam slot is formed on the arc of a circle concentric with the axis of the rock shaft 56, while the device.

- of mesh, however, as soon as upper edge of this slot is tangential of said are. This makes the slot wider at one end than -at the other, and as the push rod is actuated, it permits down into the notch in the block of the push rod, when the shaft 32 is looked, as heretofore described. In this way, the parts are all looked in operative position when the push rod is actuated and a weight has been placed on the scales. When it is desired, therefore, to register the Weight of any load, while the weight is on the scales and the pointer 4 has moved to indicate onthe dial the weight, the push rod is actuated and the pinions connecting the-two gears 24 and 26 are looked in mesh. At the same time the pinion 40 of the registering device is brought into engagement with the gear 2%, the pin 46 is Withdrawn from the pathway of the crank handle and the crank is turned in the direction of the arrow in Fig. 2 to rotate the gears and bring the pointer 4: back to zero, thus registering the amount of the weight on the counting wheels in the register Durin this movement of the operating handle, to raise the weight onthe scale; In order that the pinions rack bar 14 and with it the but this is immaterial. may be thrown out the zero point is reached, and at the same time to permit the crank handle to be returned to its normal position, I provide a pin 74 which projects laterally from the side of the gear 24, and this pin is so located. on this gear that it will come into engagement with the pawl 55 at the zero point. The pawl 55 is therefore thrown out of engagement with the pin 51 on the pinion frame, and the weight of the frame, assisted by the coiled spring 75 attached between the pinion frame andthe base plate'of the casing rocks the frame and throws" both the pinions 38 and 34 and the counter pinion 40 out of mesh with the gears. At thesame time'tlie rocking of the shaft 56 causes the cam surface of the cam slot 72 in the arm 7i to engage the pin 7 3 on the latch 68 and throw the latch out of engagement with the push rod, when it is atonce thrownback into its normal position by the coiled spring 7 8 bearing between the frame 3 and the pin, 79 on the push rod.

It frequently happens that it is desirable to obtain the net weight, instead of the gross weight, and in order to provide for deductin g the weight of the container of the article weighed, I mount 'an arm 80 with its hub 81 the latch 68 to drop the pinion 15 is also actuated loosely on the shaft 25 and the outer endfof this arm is provided with a lateral flange 82 in which is mounted a spring pin 83, in proper position for the beveled end of the pin 84; to engage the teeth of the gear 24. With this construction, before pressingthe push rod 44 to engage the pinions, in order to add on counting Wheels only the net weight, the pin 83 is pushed in to engage the gear 24, and the gear and pointer are turned back the number of graduations 114 in the casing indicated by the pointer 85, to correspond .to the weight of the container. The gear and pointer having been turned back, it is necessary for the operator to hold. the pin 8% in engagement with the teeth of the gear 24 until the push rod 44 is pressed in. When the push rod is actuated, however, the tare-deducting device can be released because the two gears 2d, 25, will then be coupled together, and the ratchet and pawl 86, 87, willprevent any back movement of the shafts. When the push rod has been pressed in, the handle will then' be given one full revolution, which adds the exact Weight only on the counting wheels.

In order to preventany back movement of the shaft 25, after the gears are connected I mount a ratchet wheel 86 on the shaft and provide a spring'pressed pawl 87 to engage, the teeth of the ratchet.

In order to prevent any one from operating the crank handle when there is no weight on the scales, I pivot on a stud 88 projecting from the face of the standard support of the shaft 25, a locking pawl 89. This .pawl is formed with an arm 90, provided with a hook 91 which engages when in normal position a pin 92 projecting from the face of the gear 26. The pawl is also provided with the slotted I gages a pin 95 projecting from the-face of the arm 71. Inasmuch as the arm 71 is pre vented from rocking by the engagement of the dog 59 with the horizontal arm 60011 the rock shaft 61, when the platform scales are in their normal position without any Weight thereon, it will be evident that the gear 26, shaft 25 and the crank" handle 28 cannot be actuated until the lever 71 is released, which can only take lace when aweight has been placed upon t e scale. This prevents any improper turning of the crank handle.

In order to prevent the operation of the push rod 4% more than once for each revolution of the crank, I providea locking bar 96 to engage the pin 46. This locking bar 96 is inset in the face of the standard 3, with its lower end immediately over the crank handle pin 4d The locking bar is guided onthe stud 97 engaging in the slot 98 in the bar, and the upper end of the bar 96 has slotted engagement over the shaft 25, and on its projecti end carries the pin 99, which is engage d @Ithe cam 100 on the collar 101,

arm 93, the slot 94: in which enpinned to the shaft This cam is so anisin, so that it can he used. whenever deranged that when the shaft and crank ed, and its use avoids the necessity of sethandlc are in their normal positions, the ting down the gross weight and deducting locking bar 96 will he raised by the can). out the-tare, as is usual with ordinary scales,

of engagement with the pin 4:6. T he pin l6,

however, is provided. with notch 102. When the pin is released and the crank turned, the cam is withdrawn from under the pin on the locking bar, and a spring 103 mounted in a in the face of the standard and hearing on an inwardly projecting stud 10 1- on the locking presses the locking oar downwardly, so that the n1omerit the pin 46 is released by the return of the dial pointer and its operating mechanism to zero, the oin 46 returns to its normal position, and the locking loar 96 engages in the not-ch in the pin, thus locking the pin and preventing any further movement of the push rod. until the crank handle has been given a full revolution to cum the locking bar out of engagement with the pinilli.

It is thought.- that from the foregoing dc- SCI'lPl'lOil the operation of the apparatus will heisufiiciently clear. .irticles are automatically weighed on the scales in the usual Way, when it is not desired to register the weights on the counting wheels, as the weighing de. vices are entirely independent of the tare deducting and total adding mechanism. When any goods are weighed concerning which it is d csii ed to keep a IQCOI'il,-Wll6fl the goods are iylaced on the scales, the rod is pushed in, the locking" pawl for the pinion frame is released and. the pinions and shaft loch tl e gears and 26 together with the total add ing pinion v 'hecl lO in mesh with the 2%.. In the event that net weight only is to be registered, before the push rod is actuated, the amount of the container which has been before that time ascertained, is deducted by actuating the arm 80. Then the latch 46 being removed from the pathway of the crank handle the handle is rotated to turn back the dial pointer to zero and register the Weight on the counting Wll-BGlS. is soon as the zero point reached, the pin is throws describes.

out the locking pawl, the pinions are disconnected and the handle can be carried around to its normai position without further registratnici. To prevent any unauthorized person :l'roni turning" the crank when no weight is tobe recorded, the crank, as heretofore described, normally locked. from being turned by the locking pawl in einent. with the gear i L Moreover, to

This movement also turns back the indicat ing pointer 4; the number of pounds to'be deducted so that the operator obtains the net weight directly from the dial without the necessity of any calculation.
